ok, here's a short term E3 report.
The KK seems to be a lot more responsive, and I noticed it too, if I push on the acellerator pedal lightly, but not enough to cause it to downshift.
Yeah, yeah, maybe it would have been the same with any old plug, but I'm just sayin'
Also, and this seems to be a biggie to me... my wife drives the KK a LOT around town.
I need to give her a new name, like "lead foot Lilly" or something, she drives very aggressively. I know she flies up to a stop sign and slams on the brakes. She goes around corners way too fast. There's a long curve on the road to our house.. When we leave home, she's going so fast that she has to slam on the brakes to go around the corner, then cut over into the opposite late just to get around it. I am always telling her to ease up a bit. I firmly believe that she is the reason that my rears brakes wore out in 35k miles. She doesn't seem to know any way to take off from a dead stop, except pedal to the metal.
Anyway.. usually, if she has the car a lot, I'll notice that the we only get about 255 to 260 miles to a tank of gas before refilling. This time, with the E3's, we got 286! YES!
This was not a scientfic calculation of any type, again, I'm just sayin'
So far, the E3's are working well..
